  === GroomServer ===
  
- A [[GroomServer|Groom Server]] (shortly referred to as groom) is a process that manages
life cycle of bsp tasks assigned by BSPMaster. Each groom contacts the BSPMaster, and reports
task statuses by means of periodical piggybacks with BSPMaster. Each groom is designed to
run with HDFS or other distributed storages. Basically, a groom server and a data node should
be run on one physical node to get the best performance for data-locality. However, in a massive
parallel environment, the benefit of data locality is lost when large amount of virtual processes
must be multiplexed onto physical processes[2].
